Why wear them

What you'll actually notice

Small changes, worn consistently. Here's where blue light glasses tend to earn their place in a day.

Easier evenings

Filter blue light in the hours before bed and give your natural wind-down a clearer run - the strongest reason to reach for a warmer tint.

Comfier screen time

Long day on the laptop? A tinted lens takes the edge off harsh screen light, so your eyes feel less worked by the evening.

Less glare

Cuts the sharp glare from monitors and bright LED lighting for a softer, steadier view.

A tint for every moment

One range, deep orange to near-clear - so there's a lens for late nights, all-day focus and everything between.

Blue light glasses support your routine - they're not a medical device. Evidence is strongest for evening use and sleep; individual results vary. If you have ongoing eye discomfort, see an optometrist.

Find your tint

From deep orange to near-clear

The tint sets how much blue light the lens filters — and when you'd wear it. Warmer for winding down, clearer for the working day.

The science

How blue light glasses actually work

Screens, LED lighting and the midday sun all throw out blue light. Our tinted lenses filter a portion of it before it reaches your eyes - how much depends on the tint.

380nm · violet-blue700nm · red

Blue light is the high-energy band around 415–455nm. It's the part most linked to alertness by day - and to delayed sleep at night. That's the band our lenses are built to filter.

Where it comes from

Phones, laptops, TVs and LED bulbs all emit blue light - and you're looking at them for hours, often late into the evening.

Why it matters

Blue light is high-energy. By day it helps keep you alert; in the evening it can tell your brain it's still daytime and hold back the melatonin that helps you drift off.

What the lens does

Each lens carries a tint that absorbs a share of the blue band before it reaches your eyes. A deeper amber tint filters more; a clearer lens filters less.

The payoff

Wear a warmer tint in the evening to protect wind-down, or a lighter one through the day for easier screen sessions. Match the tint to the moment.
